CULTIVATOR-BLADE ATTACHMENT.

To all whom it may concern. W

Be it known that I, WILLIAM OANTRELLE, a citizen of the United States,residing at Lockport, in the parish of Lafourche and State of Louisiana,have invented a new and useful Cultivator Blade Attachment, of which thefollowing is a specification.

This invention relates to agricultural implements and more particularlyto cultivator blade attachments.

This invention has for its object to provide a simple, eflicient andsubstantial cultivator attachment adapted to be secured to the beam ofany common plow and cultivator and adapted to have blade standards orshanks secured thereto.

Vith the above and other objects in View this invention is embodied inthe novel arrangement construction and combination of parts ashereinafter described and shown in the accompanying drawings, in whichsimi lar reference characters indicate similar parts, and in which,

Figure 1 is a perspective of a plow frame with the attachment securedthereto, parts broken away. Fig. 2 is a plan view of the attachment.

Referring specifically to the drawings, 5 designates the beam of theplow frame and 26 the handles secured to the rear end thereof, as arecommon in plows and cultivator constructions.

The body of the attachment comprises a flat bar of metal forged to forma central horizontal portion 15 and lateral vertical wings 16. Thecentral or intermediate portion 15 resting against the bottom of thebeam has a pair of upstanding bolts 19 in spaced relation with eachother, which are adapted to pass over the sides of the beam 5 andreceive clips 20 on their upper ends which extend across the top of thebeam to clamp the beam securely between the clips 20 and the portion 15by means of the nut 21 provided on the upper ends, of the bolts. Thisforms a convenient means for securing the attachment to the beam of aplow, or other structure. The wings 16 are provided with elongatedhorizontal slots 17 and are provided on their forward faces with aplurality of vertical flutes or corrugations 18 adjacent the edges ofthe slot 17. A U- shaped strap 12 is arranged in front of each wing 6and has rearwardly projecting bolts 23 extending from the ends thereofthrough the slot 17 and on the rear end of the bolts Specification ofLetters Patent.

is mounted a washer 25 upon which the nuts 21 bear to draw the strapinward or rearward. Standards or shanks 13 carrying the blades or earthengaging members 14 on their lower ends are adapted to pass through thestrap 12 and upon nuts 24 being tightened the same are securely clampedto the wings. When the nuts 24 are loosened the strap may be shiftedlaterally for adjusting the blades laterally as may be desired. The

corrugations 18 serve to hold the standards or shanks 13 in position,the ends of the strap 12 engaging in the said corrugations. The U-shapedstraps in receiving the standards and upon the nuts 24: being tightenedcause the standards to be clamped against the wings of the attachmentand the ends of said straps engage in the flutes 18 to prevent thehorizontal movement of the standard. Thus upon loosening the said nutsthe straps may be adjusted horizontally. The horizontal slot 17 extendsthrough the vertical sides of the wings 16 andthe flutes 18 are arrangedin one side of the said wings, it being understood that the standardsare clamped against the corresponding vertical sides of the wings withthe said flutes.

At the outer end of each wing 16 is secured a vertical strip 22 havingthe upper eye 9' and the lower eye 8. Guides 7 are connected to the eyes8 and are secured at their front ends to the front end of the beam 5 bymeans of a staple 6 or in any other manner, and rods 10 are connected tothe respective eyes 9 and extend rearwardly, being secured to thehandles 26 by means of a staple 11 or in any other suitable manner. Therods 7 connecting the lower edge of the wings with the forward end ofthe beam 5 and the rod'lO connecting the upper edge of the wings withthe rear portion of the plow frame overcome the tendency of the wings totwist upon the blade 14: engaging the earth as the beam is drawnforward, and being secured to the ends of the win s also prevent themfrom swinging in a horizontal plane.

As is apparent from the above description this attachment can be readilyapplied to various types of plow frames or the like and the objects areattained in a convenient and eflicient manner.

What is claimed is An attachment of the character described comprising abody having vertical wings provided with elongated horizontal slotstherein extending through the vertical sides of the Wings and aplurality of vertical flutes in one side of the Wings along the edges ofthe slots, U-shaped straps adapted to receive standards and having boltsprojecting from the ends thereof through the tical sides of the saidWings and the ends of the straps engage in the said flutes to preventhorizontal movement of the standards.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature 15 in the presence of two Witnesses.
